The keyboard is semi-weighted, with velocity and mono pressure aftertouch. Inside are an Engine Board, RAM, and a Sound ROM (U15 or U16). The service manual covers removing the top cover and getting at those parts. The unit takes a polyphony expansion board, and the operating system updates from a MIDI file.
